摘要
数字化变电站中保护装置采样由自我控制的模拟数据(AD)采样转变为间接的通讯获取。分析了这种转变对保护采样值(SV)接口模块研发的新要求,建立了SV模型,分析了其映射实现并研究了采样及采样同步技术。最后对基于大型可编程逻辑器件(FPGA)及同步串口(SPORT)总线技术研制的SV单元模块软、硬件结构进行了设计说明,该模块可根据装置需要多重配置,适用于各种类型数字化保护。
In digital protection,sampling methods changed by self-AD samples for indirect communication.This paper analyzes new requirements caused by shift to the protection of research and development of sampling value interface module.Though establishing sampling value models,analyzes its mapping and synchronization sampling techniques.At last software and hardware structure of sampling unit module based on large FPGA and SPORT technology is introduced.The module can apply to different types of digital protection according to appliance needs and multiple configurations
